Anyone notice an RPM up and down surge at 2300 - 2400 RPM.
Likely only notice cause I was trying to back into a tight spot. I have since put it on a stand and as the RPM are increased to 2300/2400 it surges back and forth. Hard to tell how many RPM it cycles. When increasing RPM slowly it doesn't seem very smooth either.
Going to dealer tomorrow for reverse update so I'll ask.

Mine at start up sounds like it has a bad #*$&@ cam in it. Then it goes away once it warms up.

Ya that's kind of weird. Does it do it at idle or while moving, maybe join the clutching issues?

Well good to hear! You dodged a big one there...lol... Maybe a mapping issue, that "should" be fixed as the 2015's have a reflash to the ECU.
